refactor(panel): selector de emoji y color reutilizable

Extrae app-emoji-picker y app-color-picker a shared/ y los usa en las
pestañas de niños, materiales, rutinas y recompensas, que tenían el mismo
problema: input de color a pelo y emoji escrito a mano. Ahora se elige el
icono de una rejilla de emojis y el color de la paleta del handoff.
